Optimize your signal combining and separation with the Holland Mini Diplexer, an approved device by DISH Network & DIRECTV. This gadget offers low-loss diplexing of DBS and TV signals, efficiently separating them before they reach the satellite receiver input while allowing the unison of off-air/CATV and satellite signals on a single cable. Designed to filter harmonics in the off-air spectrum and featuring an outdoor case, it ensures high isolation with low insertion loss, although it's noteworthy that it’s not intended for Dish Pro Plus installations.
